Challenge: Matching power consumption of 2600k/2700k @5ghz with a 3770k on phase change. - Page 3

2500k @ 5Ghz = Full load is 311w ( 16Mhz per 1w of power )

3770k @ 4.8Ghz = Full load is 244w ( 19.6Mhz per 1w of power )

Estimated 3770k @ 311w load = 6095Mhz

Really rough calculations here but will vary from chip to chip and will affected by Vcore.

4.8Ghz = 244w @ load

244w/4800Mhz = 0.05083

0.05083*6000Mhz = 305w of heat at load while running at 6Ghz

~305w would be on the absolute maximum a single stage can cope with safely, again this might increase depending the chip and the Vcore used, in could in theory be way above 300w

Single stage phase units pull roughtly 1:1 ratio of power to heat cooled.

So a 6Ghz Ivy would be 305w for the CPU + 305w for the phase unit

Total of 610w power consumption in a 'best case' scenario

But as already indicated by SDumper and FTW 420 a cascade system would more then likely need to be used to keep the cheap cool for 24/7 operation, these can consume way over 1000w under load.

Single stage :

$500+ for the parts to make the single stage ( Not including labor )
~610w power consumption

Cascade :

Up to $2000 for parts to make the system ( Not including labor )
1600w+ power consumption

Disclaimer : All the above calculations are a load of crap because nothing ever scales quite so linear.

It would vary from place to place, I can't really be bothered to note all the prices and the parts, doing a google search you should be able to find a list but the prices I quoted are the average prices of materials.

That unit you posted is a good clean unit, but it's a rotary compressor and uses more power and are bigger then more traditional compressors.

Rotary compressors are generally used for bigger builds as they're stronger then traditional compressors.

Look up little devils units.

As a builder, I can validate that his price guesses are close if not LOW. We can at times ebay up parts, but its far from consistent enough to produce product lines.
And when you do have to go retail to get a credible consistent source, that price can clear $3000 with labor.

Many of us have done budget work, or straight ebay parting at times, but thats generally only when our benches our empty, or our inventory is over stocked; and then we're just liquidating it and hoping to make back basic or half of labor costs.

Your question from the start was wrong and your validating it and changing it.

You cannot fit a phase unit in the space between power consumption of Sandy to Ivy. You won't get 6ghz out of every chip. And even with yours, to ask us what the power consumption would be for a certain overclock is silly and misunderstanding. YOU have to tell US what your load is. It's not something that bakes out of a calculation, you need to measure your power consumption and tell US what you need.

After all, this maybe a forum to ask questions, but this area is for people trying to learn to BUILD these things. Not necessarily for you to just ask about a random pricing and what is necessary so that you can then antagonize a builder and walk away when you realize it will cost you quite a bit.


*breathes out*

Now if you'd like to read some stickys, get a basic understanding of vapor phase change, and want to ask some questions about how to go about building one.

Feel free.

Mr Frosty is pretty spot on although cascades usually run from 1600 up depending on the use of TXV and Floated Oil seps...
